Duo group (resident main+subagent for pi): flip VRAM to the small model.
Ornith experts never touch VRAM; its dense-on-GPU split starved qwen to
176 MiB / 5.8 t/s concurrent. After flip: qwen 43 t/s, ornith 8 t/s.
CUDA_VISIBLE_DEVICES= required for ornith — ngl 0 still allocates ~1GB
pp compute buffer on CUDA builds (OOM+segfault). Duo section in
MOE-FINDINGS.md; also snapshots prior swap-stack migration state.
